Y

The central rod 1 of the hair Waver has a tube 2 Y mounted thereon for rotary move- 5 ment in one direction only and also :tor limited endwise movement on which tube the tress is wound` and secured. The outer end of the rod is provided with Va head 3 Xedly secured thereto and the inner end ofthe rod 5 has a tress engaging arm 4 rotatablymounttaken in 1929. semaine. 363,261.v l

ed thereon. Y rihe inner end of the rod also has an axially screw threaded bore v5 which is vengaged by a screw 6 which-'projects out#` wardly from a scalp member, which, inthe `'present instance, is represented as a plate T, fromwhich scalp plate also projects a tress engaging pin. 8 parallel with the screw 6.@

rlhe swinging arm 4 is broughtinto and out of coactive relationship with the pin Saas thel rod 1 is yscrewed inwardly and outwardly. This swinging arm 4 is shown as having a recess `9, adapted to seat thepin 8 therein when broughtv into coaction therewith.

rlhescalpplate is preferablyimbedded in a shield 10 of yielding vvheat insulating material,` such as soft rubber, for cushioning the device and also for preventing the plate'V from coming into directk Contact' with the scalp. Y .v

For facilitatingthe application of the tress to the device, the scalp plate has a flattenedv edge portion 11 and the shield has a corre-y 'A sponding ,iiattened edge portion v12'.

rlhe tube, 2 is` preferably provided with a gradually tapered innerk end portion 13 and anenlarged outer end portion 14, the periph'- eral surface oi which outer 'end portion may be milled vor otherwise roughened,zto facil; itate the operation of the device.`

This tube 2 is free to turn on the rod .1 in Vone direction but is held againsttu'rning on the rod in the opposite direction by a clutch, which, in the present'instance, comprises a coil spring 15. surrounding the rod within the bore of a sleeve v16, located within the enlarged outer end portion 14 of the tube Y and lockedthereto by a lug 17 which is located in a slot y18 in the tube. One end of this clutch spring 15 is secured to the sleeve so that when the sleeve and tube-are turned inione di rection, the coils of the spring will free themselves from the rod and when turned in the other direction, th'efcoilswill grip the rod to clutch .the sleeve and'tubethereto.

Means are provided or yieldingly holding .the tube at the limit ofits inward sliding movement on the rod with the inner end oi the tube in engagement with the circumferential shoulder 19` on the rod',fwhich means 1s herein shownas comprising an expansion In operation z-In applying thewaverto the head, the rod 1 is turned in a direction to unscrew the rod from the scalp plate 6 suiiciently to permit a tress of hair to be passed between the screw and the scalp plate pin 8. The rod'is their turned in the direction to screw the rod toward the scalp plate sufficiently to bring the pin 8 and armtinto coactive' relationship. The arm is then swung around into engagement with the pin and the tress may then bepassed around the arm and also around the tube and secured in this position by any well known or approved meansas, for instance, by wrapping a tape 24 around the so coiled tress. The tube may then be rotated' on the rod-in a direction to tighten the coils of the tress, it being understood that the clutch spring l5 will hold the tress coilsin their-tightenedposition by preventing the reverse turning movement of the tube on the rod.l

' A heating unitfof any well known or approved construction (not shown herein) may then be applied to the device for the desired time and then removed.

`To remove the device from the tress, the tress is loosened from the tape and rod and the tube is then drawn Youtwardly along the rod until it is-interlo'cked with the head 8 ot' the rod by the coaction of the lugs 22 and recesses '23. The tube and rod may then be turned together ina direction which will unscrew the rod from the scalp plate screw and thus permit the removal of the rod and tube therefrom. The scalp plate may then be. removed and again connected to the'rod for a subsequent operation. y

It is evident that various changes'may be resorted to in the construction, form andarrangement Vof the several parts without departing from the spirit and scope of my invention; hence, I do not intend to be limited to the particular embodiment herein shown and described, but what I claim is l.
